Hi,
This series has expanded from v2 based on the feedbacks. Main items happening in
this series are:
1. KVM MMU shrinker now shrinks KVM caches.
MMU shrinker will free shadow page caches and split caches whenever shrinker
is invoked.
2. Page table's pages are allocated on NUMA node during fault and split.
Pages of page tables will be allocated based on the underlying physical page
a page table entry is point to. Got performance improvement up to 150% in
416 vCPUs VM during live migrations.
3. Cache size is reduced from 40 to 5.
40 is current cache size for KVM memory caches. Reduced them to 5. I didn't
see any negative performance impact while running perf and dirty_log_perf_test.
I also saw lesser number of calls to get a free page.
Thanks
Vipin
v3:
- Split patches into smaller ones.
- Repurposed KVM MMU shrinker to free cache pages instead of oldest page table
pages
- Reduced cache size from 40 to 5
- Removed __weak function and initializing node value in all architectures.
- Some name changes.
v2: https://lore.kernel.org/lkml/20221201195718.1409782-1-vipinsh@google.com/
- All page table pages will be allocated on underlying physical page's
NUMA node.
- Introduced module parameter, numa_aware_pagetable, to disable this
feature.
- Using kvm_pfn_to_refcounted_page to get page from a pfn.
v1: https://lore.kernel.org/all/20220801151928.270380-1-vipinsh@google.com/

mmu_shrink_scan() is very disruptive to VMs. It picks the first
VM in the vm_list, zaps the oldest page which is most likely an upper
level SPTEs and most like to be reused. Prior to TDP MMU, this is even
more disruptive in nested VMs case, considering L1 SPTEs will be the
oldest even though most of the entries are for L2 SPTEs.
As discussed in
https://lore.kernel.org/lkml/Y45dldZnI6OIf+a5@google.com/
shrinker logic has not be very useful in actually keeping VMs performant
and reducing memory usage.
Change mmu_shrink_scan() to free pages from the vCPU's shadow page
cache. Freeing pages from cache doesn't cause vCPU exits, therefore, a
VM's performance should not be affected.
This also allows to change cache capacities without worrying too much
about high memory usage in cache.
Tested this change by running dirty_log_perf_test while dropping cache
via "echo 2 > /proc/sys/vm/drop_caches" at 1 second interval
continuously. There were WARN_ON(!mc->nobjs) messages printed in kernel
logs from kvm_mmu_memory_cache_alloc(), which is expected.

zapped_obsolete_pages list was used in struct kvm_arch{} to provide
pages for KVM MMU shrinker. This is not needed now as KVM MMU shrinker
has been repurposed to free shadow page caches and not
zapped_obsolete_pages.
Remove zapped_obsolete_pages from struct kvm_arch{} and use local list
in kvm_zap_obsolete_pages().

split_shadow_page_cache is not used after dirty log is disabled. It is a
good candidate to free memory in case of mmu_shrink_scan kicks in.
Account for split_shadow_page_cache via kvm_total_unused_mmu_pages and
use it in mmu_shrink_scan.

When dirty log is enabled, huge pages are split. Page table's pages
during the split are allocated based on the current thread NUMA node or
mempolicy. This causes inefficient page table accesses if underlying
page is on a different NUMA node
Allocate page table's pages on the same NUMA node as the underlying huge
page when dirty log is enabled and huge pages are split.
The performance gain during the pre-copy phase of live migrations of a
416 vCPUs and 11 TiB memory VM on a 8 node host was seen in the range
of 130% to 150%.

Add 'node' variable in kvm_mmu_memory_cache{} to denote which NUMA node
this cache should allocate memory from. Default initialize to
NUMA_NO_NODE in all architectures.

Page table pages of a VM are currently allocated based on the current
task's NUMA node or its mempolicy. This can cause suboptimal remote
accesses by the vCPU if it is accessing physical pages local to its NUMA
node but the page table pages mapping those physcal pages were created
by some other vCPU which was on different NUMA node or had different
policy.
Allocate page table pages on the same NUMA node where underlying
physical page exists. Page table at level 5, 4, and 3 might not end up
on the same NUMA node as they can span multiple NUMA nodes.

KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE is set to 40 without any specific
reason. Reduce default size to PT64_ROOT_MAX_LEVEL, which is currently
5.
Change mmu_pte_list_desc_cache size to what is needed as it is more than
5 but way less than 40.
Tested by running dirty_log_perf_test on both tdp and shadow MMU with 48
vcpu and 2GB/vcpu size on a 2 NUMA node machine. No impact on
performance noticed.
Ran perf on dirty_log_perf_test and found kvm_mmu_get_free_page() calls
reduced by ~3300 which is near to 48 (vcpus) * 2 (nodes) * 35 (cache
size).

Oh, that's not a good thing. I don't think we want to be hitting those
warnings. For one, kernel warnings should not be expected behavior,
probably for many reasons, but at least because Syzbot will find it.
In this particular case, we don't want to hit that because in that
case we'll try to do a GFP_ATOMIC, which can fail, and if it fails,
we'll BUG:
void *kvm_mmu_memory_cache_alloc(struct kvm_mmu_memory_cache *mc)
{
void *p;
if (WARN_ON(!mc->nobjs))
p = mmu_memory_cache_alloc_obj(mc, GFP_ATOMIC | __GFP_ACCOUNT);
else
p = mc->objects[--mc->nobjs];
BUG_ON(!p);
return p;
}
Perhaps the risk of actually panicking is small, but it probably
indicates that we need better error handling around failed allocations
from the cache.
Or, the slightly less elegant approach might be to just hold the cache
lock around the cache topup and use of pages from the cache, but
adding better error handling would probably be cleaner.

Again, this will cause a null-pointer dereference. The check above

I think we still want to do the SRCU read lock here to prevent
use-after-free on the vCPUs.

Would it make sense to just have kvm_mmu_empty_memory_cache()
decrement the per-cpu counter itself? I don't think there's much perf
to be gained by reducing percpu counter updates here and it would
consolidate the bookkeeping.

This will return 0 if the sum of all the per-cpu counters is negative.
It should never be negative though. Might be nice to add a warning if
we would get a negative sum.

Just so that kvm_mmu_get_free_page isn't dead code in the previous
commit, I'd do this refactor there and just pass NUMA_NO_NODE here.

This could just be kvm_pfn_nid (or even better kvm_pfn_node_id) since
this really has nothing to do with page tables. We just want to know
which NUMA node backs the given PFN.

It looks weird to have MIPS not using the initialization MACRO. Should
it just have a GFP_ZERO parameter?

Given that this initialization is probably not happening in a super
hot path, is there any downside to just using a function for the

A page table at any level could map memory spanning multiple NUMA
nodes, it just becomes more likely at higher levels.
We're only guaranteed that a page table maps memory all on the same
node if it's a split hugepage.
This change can only guarantee that the page table pages are allocated
on the same node as at least some of the memory they map.
Of course in practice, the above is absolutely correct since we'd
expect to have multi-GB continuous ranges of GFNs allocated on the
same node via huge pages.
And since the root pages are allocated based only on where the thread
allocating them is running, they're not actually guaranteed to be on
the same node as any of the memory they map. (Though they probably
will be.)

Was just trying to think if there could be any issue with memory
leakage if the online nodes changed, though IDK if any hardware does
that.
Still, it might be more robust to use ARRAY_SIZE and cover the whole array.

Is there any reason to keep the cache if !node_online(nid)?
Actually, I'd also just drop the cache_count argument and always
iterate over the entire array, only checking nobjs. There's no
guarantee I'm aware of that the set of nodes has a sequential series
of IDs starting at 0 and you'd get a bug if that wasn't the case since
it only iterates to nid < cache_count here but some of the earlier
nids might not have been online.

So lonely.
One.

Might be worth calling out somewhere that the root page is just
allocated based on where the thread allocating it runs.

You could do part of this change in the commit that introduced

Again, assuming no one sets CONFIG_NODE_SHIFT to a ridiculous value,
it would probably be fine to initialize the entire array here since
that doesn't take any extra memory and we're not in a super hot path.

Why do you say more than 5? At least to resolve a page fault we'll
never need more than 4 pages on a system with 5 level paging since the
root is already allocated.

I was counting on the fact that shrinker will ideally run only in
extreme cases, i.e. host is running on low memory. So, this WARN_ON
will only be rarely used. I was not aware of Syzbot, it seems like it
will be a concern if it does this kind of testing.
I thought about keeping a mutex, taking it during topup and releasing
it after the whole operation is done but I stopped it as the duration
of holding mutex will be long and might block the memory shrinker
longer. I am not sure though, if this is a valid concern.
I can't think of a better error handling in this situation. I can
change logic to hold mutex if the above mutex hold duration concern
won't be an issue compared to the current WARN_ON() approach.

Yes, I forgot to change it in the commit and one patch later in the
series removes this whole "if(!cache_lock)" condition so it skipped my
attention. Thanks for catching it.

Since I am in mutex_lock(&kvm_lock), a kvm will not be removed from
kvm->vm_list, this will block kvm_destroy_vm() moving further to
destroy vcpus via kvm_arch_destroy_vm() > kvm_destroy_vcpus(). Do we
still need the srcu_read_lock()? Also, kvm_for_each_vcpu() using
xa_for_each_range() which uses RCU for traversing the loop, won't
these two be sufficient to avoid needing srcu_read_lock() here?

kvm_mmu_empty_memory_cache() is also used by other caches for which
are not keeping the count.

I will say "current thread CPU". As memory nodes are near to CPUs
whereas threads can execute on multiple CPUs throughout its lifetime.

Apart from NUMA node backing the given PFN, it can also return the
nearest NUMA node via numa_mem_id(). So, it is actually telling which
NUMA node is the best one for the page table's page, given a PFN.

MIPS is not setting GFP_ZERO explicitly before my series, so, I didn't
make it GFP_ZERO. I am not sure if MIPS needs it or not, I tried to
keep the same functionality in my patch.
May be someone from MIPS can tell more about it.

for_each_node() goes through all of the possible nodes on the system,
whereas, for_each_online_node() goes through only online nodes.
Current code seems right to me, let me know if I am overlooking
something.

This is just temporary and will be removed in the next patch in the series.
mmu_shrink_cache() is used for both split_shadow_page_cache (single
object) and mmu_shadow_page_cache[MAX_NUMANODES].
In next patch of this series, I used for_each_online_node(nide), I
will change it to for_each_node() in the next version.

How about a comment just up here or do you prefer at tdp_mmu_roots in

Yeah, I can do it there as well. No strong opinions. I will update in

This goes through the entire array. I think you are confusing it with
for_each_online_node().

Git diff is showing it weirdly. They are aligned to "struct kvm *kvm"
and both will be on different lines to keep them in the 80 char limit.

That makes sense, I just don't want to see MIPS get left behind
because we move the cache init logic to a macro or function. Folks
might update the init function but forget to update MIPS too.

In an extreme low-memory situation, forcing vCPUS to do GFP_ATOMIC
allocations to handle page faults is risky. Plus it's a waste of time to
free that memory since it's just going to get immediately reallocated.

Use mutex_trylock() to skip any vCPUs that are currently handling page
faults.

Can you split this commit up? e.g. First drop the old shrinking logic in
one commit (but leave the shrinking infrastructure in place). Then a
commit to make the shrinker free the per-vCPU shadow page caches. And
then perhaps another to make the shrinker free the per-VM shadow page
cache used for eager splitting.

It would be nice to avoid adding these wrapper functions.
Once you add a mutex to protect the caches from being freed while vCPUs
are in the middle of a page fault you can drop the spin lock. After that
the only reason to have these wrappers is to update
kvm_total_unused_mmu_pages.
Do we really need kvm_total_unused_mmu_pages? Why not just dynamically
calculate the number of of unused pages in mmu_shrink_count()? Or just
estimate the count, e.g. num_vcpus * KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE?
Or have per-VM or per-vCPU shrinkers to avoid needing to do any
aggregation?

optional nit: The common name of this is invalid_list (see other callers

Generally it's not good practice to introduce dead code. So I would
request merging this with the next patch.

Can you be more specific about this. "The performance" is vague. I know
it's an internal workload and fully explaining it would be difficult,
but you can give readers a slightly more specific idea of what improved.
e.g.
When testing with a synthetic write-heavy workload in a 416 vCPU VM on
an 8 NUMA node host, the throughput increased by 150% from X to Y
operations per second.
It's also necessary to characterize the improvement relative to the
performance when dirty logging is not enabled. Whithout that information
it would be hard for an unfamiliar reader to understand how useful this
change really is.
For example, let's say the throughput of your workload is 100,000
operations per second before dirty logging is enabled, and that drops
down to 1,000 operations per second after dirty logging is enabled. This
commit could increase that by 150% to 2,500 operations per second, but
that's actually not a very meaningful improvement since, either way,
guest performance is degraded by 95+% during dirty logging.
On the other hand, if performance goes from 100,000 to 30,000 normally,
and this commit increases that 30,000 to 75,000 (150%), that's a much
more meaningful improvement.

I know what you are trying to say but the wording is a bit awkward. e.g.
"Tells" instead of "Returns", "location" is redundant, "page table's
page", etc. Suggest this:
/*
* Returns an appropriate NUMA node on which to allocate a page table that
* maps @pfn.
*/

I would just drop this as it's just restating the code, which is already
very readable.

This is not any better than setting cache.node = NUMA_NO_NODE directly.
Yes it's less lines of code, but it's harder to read (what does NULL
mean here?), and every user of kvm_mmu_memory_cache still has to know to
pass NUMA_NO_NODE.
When I originally gave this suggestion, I intended to suggest that
INIT_KVM_MMU_MEMORY_CACHE() provide just default initialization.
Non-default initialization for gfp_zero, gfp_custom, kmem_cache, and
node would remain as they are.
Yes this adds some more lines, but keeps things readable, and doesn't
every initialization site of kvm_mmu_memory_cache to know what to pass
for gfp_zero, node, and kmem_cache. It only needs to set the fields
*it* cares about.
Here's what I mean specifically, based on INIT_LIST_HEAD. I don't think
I got all the kvm_mmu_memory_cache users, but you get the point.

And to offset the extra lines to call INIT_KVM_MMU_MEMORY_CACHE(), we
could finally invert the meaning of gfp_zero so that caches use
__GFP_ZERO by default. The majority of caches want __GFP_ZERO, so that
should cut down a bunch of lines.

Hi Huacai, Aleksandar,
I have noticed that MIPS doesn't use __GFP_ZERO flag for
mmu_page_cache in KVM. Is it intentional? I was wondering if it will
be useful if I add zero flag for cache in this patch for MIPS? All
other architectures seem to use __GFP_ZERO flag for their caches.
Thanks

Sounds good, I will separate it in two parts, one for dropping old
logic, one for adding per vcpu shadow page caches. Patch 3 is enabling
shrinkerto free per-VM shadow page.

I think we can drop this, by default we can return num_kvms *
num_vcpus * nodes * KVM_ARCH_NR_OBJS_PER_MEMORY_CACHE
Whenever mmu_shrink_scan() is called if there are no pages to free
then return SHRINK_STOP which will stop any subsequent calls during
that time.

When I wrote that comment I was thinking you can change `gfp_t
gfp_zero` to e.g. `bool skip_gfp_zero` so that the default initialized
value (false/0) means "use __GFP_ZERO".
However, that's silly once we have INIT_KVM_MMU_MEMORY_CACHE(). We can
do what you suggest: set gfp_zero to __GFP_ZERO in
INIT_KVM_MMU_MEMORY_CACHE() and then explicitly set it to 0 in caches
that don't need __GFP_ZERO.

I think the mmu_cache allocation and deallocation may cause the usage
of GFP_ATOMIC (as observed by other reviewers as well). Adding a new
lock would definitely sound like a plan, but I think it might affect
the performance. Alternatively, I am wondering if we could use a
mmu_cache_sequence similar to mmu_notifier_seq to help avoid the
concurrency?
Similar to mmu_notifier_seq, mmu_cache_sequence should be protected by
mmu write lock. In the page fault path, each vcpu has to collect a
snapshot of mmu_cache_sequence before calling into
mmu_topup_memory_caches() and check the value again when holding the
mmu lock. If the value is different, that means the mmu_shrinker has
removed the cache objects and because of that, the vcpu should retry.

vCPU deletion:
We take kvm_lock in mmu_shrink_scan(), the same lock is taken in
kvm_destroy_vm() to remove a vm from vm_list. So, once we are
iterating vm_list we will not see any VM removal which will means no
vcpu removal.
I didn't find any other code for vCPU deletion except failures during
VM and VCPU set up. A VM is only added to vm_list after successful
creation.
vCPU creation:
I think it will work.
kvm_vm_ioctl_create_vcpus() initializes the vcpu, adds it to
kvm->vcpu_array which is of the type xarray and is managed by RCU.
After this online_vcpus is incremented. So, kvm_for_each_vcpu() which
uses RCU to read entries, if it sees incremented online_vcpus value
then it will also sees all of the vcpu initialization.
@Sean, Paolo
Is the above explanation correct, kvm_for_each_vcpu() is safe without any lock?

Can you explain more about the performance impact? Each vcpu will have
its own mutex. So, only contention will be with the mmu_shrinker. This
shrinker will use mutex_try_lock() which will not block to wait for
the lock, it will just pass on to the next vcpu. While shrinker is
holding the lock, vcpu will be blocked in the page fault path but I
think it should not have a huge impact considering it will execute
rarely and for a small time.

Yeah, this can be one approach. I think it will come down to the
performance impact of using mutex which I don't think should be a
concern.

hmm, I think you are right that there is no performance overhead by
adding a mutex and letting the shrinker using mutex_trylock(). The
point of using a sequence counter is to avoid the new lock, since
introducing a new lock will increase management burden. So unless it
is necessary, we probably should choose a simple solution first.
In this case, I think we do have such a choice and since a similar
mechanism has already been used by mmu_notifiers.

Let me take it back. The per-vcpu sequence number in this case has to
be protected by a VM level mmu write lock. I think this might be less
performant than using a per-vcpu mutex.

No, more locks doesn't necessarily mean higher maintenance cost. More complexity
definitely means more maintenance, but additional locks doesn't necessarily equate
to increased complexity.
Lockless algorithms are almost always more difficult to reason about, i.e. trying
to use a sequence counter for this case would be more complex than using a per-vCPU
mutex. The only complexity in adding another mutex is understanding why an additional
lock necessary, and IMO that's fairly easy to explain/understand (the shrinker will
almost never succeed if it has to wait for vcpu->mutex to be dropped).

The mmu_notifier case is very different. The invalidations affect the entire VM,
notifiers _must_ succeed, may or may not allowing sleeping, the readers (vCPUs)
effectively need protection while running in the guest, and practically speaking
holding a per-VM (or global) lock of any kind while a vCPU is running in the guest
is not viable, e.g. even holding kvm->srcu is disallowed.
In other words, using a traditional locking scheme to serialize guest accesses
with host-initiated page table (or memslot) updates is simply not an option.

Yep, KVM doesn't support destroying/freeing a vCPU after it's been added.

Yep. The shrinker may race with a vCPU creation, e.g. not process a just-created
vCPU, but that's totally ok in this case since the shrinker path is best effort
(and purging the caches of a newly created vCPU is likely pointless).

Well, in this case, you do need to hold kvm_lock ;-)
But yes, iterating over vCPUs without holding the per-VM kvm->lock is safe, the
caller just needs to ensure the VM can't be destroyed, i.e. either needs to hold
a reference to the VM or needs to hold kvm_lock.
